OK, it's off. I knocked up a puller from some bits of 6mm plate and
some studding. Boy, was it tight, putting a serious bend in the bits
of plate before giving way with a audible crack. I almost stopped and
re-posted here 'Are you SURE there isn't a hidden pin or screw?'

Thanks.

The key in my clone needed some major pressure to get it out so I suspect they
are fitted and then the handle hammered home :(

Should just pull off after removing the obvious nut and washer. Have
you tried loosening the nut a little and giving it a rap with a nylon
hammer while pulling on the handle?

Have a look at

http://bbs.homeshopmachinist.net/showthread.php?t=27097

where the same issue was discussed recently. The pictures of the
instruction manual (which contains an exploded parts diagram) seem to
be inaccessible just now but if you are still struggling I could scan
mine.

Force. Take the nut (or is it a bolt?), and it's just keyed onto the shaft.

Mine is still lying in bits after I stripped a few teeth of the worm wheel.
Milling a 12" circle of 1/2" steel on a 6" table wasn't my best ever idea.
